Title: A modular partition system
Inventor: DONOVAN JOHN MARTIN
IPC: E04B2/74
Filed: 1991-03-06
Abstract: A modular partition system comprising panels (11) each composed of an interior framework of frame members (14-22) which reinforce and secure together two parallel cladding layers (12, 13) of rigid material, the boundary edges of which are offset with respect to the frame members (15, 16, 20, 22) defining the boundaries of the supporting framework so as to define upper and lower channels (23, 24) and cooperating tongue (23) and groove (25) formations in the lateral edges. A partition is installed by locating a batten (28) along an original wall and a floor plate (26) having an upstanding ridge (27) in alignment therewith so that two channels (24, 25) in the lower edge and one lateral edge of the panel (11) can be engaged over the tongues thus formed to locate and interlock a panel in position. <IMAGE>

Title: Vacuum booster
Inventor: SHINOHARA TAKAYOSHI
IPC: B60T13/569
Filed: 1991-06-11
Abstract: In a vacuum booster the inner peripheral bead 3b of the diaphragm is formed into a ring shape projecting rearwardly to have its outer periphery engaged with a forwardly projecting retaining portion 17b of a stopper 17. The retaining portion 17b is formed with a curved front end so that if the diaphragm 3 is deflected towards the working chamber B (as shown by the dotted lines) damage to the diaphragm 3 is avoided; the diaphragm 3, when deflected towards the working chamber B, will urge the retaining portion 17b radially inwards thus reducing the force acting on the inner periphery bead 3b in a direction away from the piston boss 5. The stopper may be of folded sheet metal or may have a moulded resin cover 19 on a metal core 18. Rearwardly projecting lugs 17c counteract rearward forces acting on the stopper.   <IMAGE>

Patent GB-2252082-A (GB)
Title: A method of raising objects from the sea bed
Inventor: STANGROOM JAMES EDWARD
IPC: B63C7/10
Filed: 1992-01-23
Abstract: A flexible envelope, of fabric, plastic sheet or similar material, is made buoyant by being filled with water of lower salinity than the surrounding medium, and used to lift loads underwater. The lift can be generated in situ by pumping water into the envelope after it has been attached to the load through a hose from the surface, and reduced by either releasing the water from within the envelope or pumping it back to the surface again. By combining these two operations, the lift can be exactly controlled. Several envelopes can be used to lift a single load, and the load itself can be made up of small objects placed in a suitable container by other means. The envelopes may be towed into position, or may be provided with their own means of propulsion.
Patent GB-2264718-A (GB)
Title: Vapour deposited coatings having at least three transitions in structure
Inventor: MATTHEWS ALLAN
IPC: C23C14/32
Filed: 1992-03-04
Abstract: A coating process comprises forming on a substrate by physical vapour deposition a layered coating of a material, the layers including at least three transitions in structure, the process comprising varying continuously or semi-continuously the structure of each layer through the structure to prevent discontinuities between successive layers. The composition of the material may be the same or generally the same throughout the layers. The problem of inter-lamellar debonding and separation in such structures is thus overcome by the modulation of the process parameters to produce layers whose composition varies gradually to avoid shock transitions between structural zones. This can be achieved by, for example, varying continuously or semi-continuously the degree of ionization; the substrate bias voltage (Fig 2); or the chamber pressure. The degree of ionization may be controlled by ranging the electron emission from a thermionic emitter in plasma- assisted PVD; or by varying the amount of radio frequency power coupled into the plasma in a radio frequency plasma system. <IMAGE>

Title: Injecting particulate material into boreholes
Inventor: DOBSON ANDREW ROBERT
IPC: E21B43/04
Filed: 1992-08-19
Abstract: Sand or bentonite, in particulate form, is fed to an injection pipe 30 which is placed in a water filled borehole. Air from the surface is blown down the injection pipe, keeping the pipe water free, the particulates being ejected from the bottom mouth of the pipe. The sand and bentonite is used as packing around a sampling tube 20. A collar 96 shrouds the bottom mouth 56 of the injection pipe, and collects the air emerging from the pipe. An outlet pipe 36 conducts the air upwards, causing the particulates to fall and separate, whereby the particulates are not swirled and churned, but come to rest gently on the already-deposited material. Similar collars may be used to inject particulate material in boreholes with two or more sampling tubes. <IMAGE>

Title: Processing circuit
Inventor: HOLCROFT JOHN D
IPC: G01S7/292
Filed: 1992-09-07
Abstract: A digital processing circuit for a civil marine radar includes a range integration circuit 12 which averages returns over one pulse length, an interference filter 13 which compares data samples corresponding to the same positions in range and neighbouring positions in azimuth and selects the lesser of the compared values and an azimuth integration circuit 14 which averages returns over one beam - width for each range. Range integration circuit 12 may comprise a low-pass filter or a FIR filter. At short ranges (SR, fig 2), the processing circuit is replaced by a delay of half the beam dwell - time. This enables noise to be reduced, and returns resulting from other radars to be eliminated. The signal-to-noise ratio can be improved by rotating the antenna more slowly. <IMAGE>

Title: Adaptive control system and method thereof
Inventor: KIJI JUNICHI
IPC: B01J19/00
Filed: 1992-10-28
Abstract: In an adaptive control system for e.g. a chemical plant, an initial feedback gain value K0 is selected by on-line identification at 30 of the current dynamic characteristics of the controller system 10 based on input and output data u, y. The "gain sensitivity" of the system is calculated by determining the derivative of an evaluation function V relating to system characteristics, with respect to gain K. The gain is optimum when the derivative of the evaluation function is zero and the gain is finely adjusted to maintain this condition. When the gain sensitivity is determined to be greatly deviated from zero, an initialization instruction is supplied to the on-line identifier 30 to initialize the covariance matrix in the on-line identification. Thus, a satisfactory response speed and precision can be obtained even when the present invention is applied to a controlled object 10 the dynamic characteristic of which changes significantly. <IMAGE>

Title: Power feeding branching unit for submarine telecommunications systems
Inventor: WEBB STEPHEN MICHAEL
IPC: H04B10/00
Filed: 1993-03-03
Abstract: A branching unit is for use in a submarine telecommunications optical cable system which employs electrical power feeding for repeaters/regenerators, in particular a system employing multiple branching units. The unit terminates three line cables (at 1, 2, 3) and a sea earth (at 4) and includes three high voltage relays A, B, C only one of which is energised at a time. When electrical power is supplied between any two line terminations, e.g. 1 and 3, an associated relay coil, eg. C is energised so that its contacts C1 isolate the third line termination, e.g. 2, and connect it to the sea earth termination 4 via contacts D1 of a relay D if the power feed direction is from 1 to 3, or via contacts E1 of a relay E if the power feed direction is from 3 to 1. Optical regenerators (not shown), for optical path switching purposes, have series connected effectively in parallel with each of the relay coils A, B, C. When any relay A, B, C is energised, i.e. the cable system is powered up, the regenerators are also powered. Zener diodes 21 and coils 29 provide surge protection for the power feed circuits 20, relay coils and rectifiers 22, 23, 24. The fourth and fifth relays D, E serve to prevent and transfer in the changeover contacts of relays A, B, C. <IMAGE>

Title: Fluid diffuser
Inventor: ALLISON WILLIAM
IPC: C02F3/20
Filed: 1993-06-07
Abstract: A diffuser for use in submerged conditions, e.g. for aerating sewage, comprises an elongate material strip made from two separate sheets 1, 2 of synthetic plastics material which are separately perforated in two lateral zones 1a, 1b and 2a, 2b and then heat sealed together at their longitudinal edges 3, 4 and at intermediate positions 5, 6 to either side of a steel cable 7 positioned between the sheets 1 and 2. The steel cable 7 is arranged to act as a negative buoyancy aid. When air is supplied to the tubes 8, 9 they distend into an inflated condition and air passes into the surrounding medium through the tube perforations. The cable may be replaced by metal strips (77, Fig 16, not shown). Various other forms of diffusers are also disclosed, including one of circular design. The perforations are self-closing, and their proximity and the elasticity of the material are such that internal pressures cause a synchronous opening and closing of the perforations (Fig 21, not shown). <IMAGE>

Title: A direct conversion receiver
Inventor: SMITH CHRISTOPHER NIGEL
IPC: H04L27/233
Filed: 1994-02-22
Abstract: The receiver includes input means comprising an antenna and blocking filter, the output of which is connected to an amplifier. The input signal is split and mixed with an in-phase and quadrature phase signal generated by an oscillator in a mixer circuit, respectively. An output from each mixer circuit is applied to a low pass filter and to an input of a limiting circuit. The output from each low pass filter is applied to an input of a summator circuit respectively, a first of which is arrange to sum the in-phase and quadrature phase signals, and the second of which is arranged to subtract the in-phase and quadrature phase signals to generate a respective output signal having an axes intermediate of the in-phase and quadrature phase signal axes. These signals, together with the in-phase and quadrature phase signals are passed through a limiting circuit respectively, to a decoder circuit for recovering the data. The output of the limiting circuits represent signals quantised to eight possible phase states separated by 45 DEG . When the input signal is GFSK modulated the vector will always cross at least one axis, so the direction of rotation can be established prior to data recovery. In an alternative embodiment (Fig. 6 not shown) a ratiometric combiner may be used instead of the summator circuits, and this is particularly useful for PI /4-DQPSK modulation, where the phase excursion per symbol is +/- 45 DEG  or +/-135 DEG depending upon the bit pair combination, and in this embodiment a minimum of eight axes are generated giving sixteen sectors and 22.5 DEG phase resolution. <IMAGE>

Title: Mobile radio communication system capable of preventing interference between time slots when propagation delay exists
Inventor: KITO EIJI
IPC: H04W56/00
Filed: 1994-07-19
Abstract: In a time division multiplex system with a base station 21 which can transmit to mobiles 11-1 to 11-N in respective time slots of first frames and can receive from the mobiles in respective time slots of second frames which alternate with the first frames, a guard time (P, Fig. 4) is introduced between a second frame and the following first frame to avoid radio path propagation delays causing partial overlap between such frames. However, the additional propagation delay caused by the communication line 12a between a main station 23 and the base station 21 may still cause a partial frame overlap (Pov). The delay due to the line 12a is therefore determined and if it is greater than a predetermined period, a circuit 29 is operated to inhibit communication between the mobiles 11-1 to 11-N and the main station 23. A control 27a causes a test command followed by a test information signal from a command producing circuit 27b to be passed to base station 21 via switch 28 modem 15 and line 12a. Control 27a also starts a timing counter in a detecting circuit 27c. In response to the test command, a detecting circuit 25 in the base station connects the line 12a to a test circuit 26 which sends back an answer signal in response to the test information signal. The timing counter is stopped when the detecting circuit 27c receives the answer signal, whereby the propagation delay due to the line 12a can be determined. <IMAGE>
